A high-efficiency cutting device for paper cup production

Abstract

This utility model discloses a high-efficiency cutting device for paper cup production, belonging to the field of paper cup production technology. It includes a frame, with a hydraulic column fixedly installed at the top center of the frame, and a cutting blade fixedly installed at the movable bottom end of the hydraulic column. The cutting blade is located inside the upper part of the frame, and a discharge port is opened at the bottom end of the frame. A fixing seat is fixedly installed at the bottom end of the inner wall at both ends of the frame. In this utility model, when the hydraulic column extends, causing the cutting blade to fall onto the top of the blade holder, the paper in the paper cup can be cut off. The paper falls inside the discharge channel. When the air inlet pipe delivers airflow into the distribution ring, two second branch pipes spray airflow obliquely towards the top of the discharge channel, and multiple first branch pipes in two rows guide airflow into the air outlet, causing the two rows of air outlets to spray airflow obliquely downwards. This allows the paper to be discharged downwards by the two sets of airflows inside the discharge channel, facilitating the smooth and rapid discharge of the paper from the discharge channel.

Description

Technical Field

[0001] This utility model relates to the field of paper cup production technology, and in particular to a high-efficiency cutting device for paper cup production. Background Technology

[0002] Paper cups are paper containers made by mechanically processing and bonding paper (white cardboard) made from chemical wood pulp. They are shaped like cups. Paper cups for frozen foods are coated with wax and can hold ice cream, jam, butter, etc. Paper cups for hot drinks are coated with plastic, can withstand temperatures above 90℃, and can even hold boiling water. Paper cups are characterized by safety, hygiene, lightness, and convenience. They can be used in public places, restaurants, and cafes, and are disposable items. In the production and processing of paper cups, paper needs to be cut into fan-shaped cup pieces, and then the stacked cup pieces are placed on paper cup making equipment for further processing.

[0003] A search revealed a patent with publication number CN217729813U entitled "A High-Efficiency Cutting Device for Paper Cup Production." The technical problem it addresses is the low efficiency of paper cup production caused by the need for manual stacking of cut cup pieces after cutting. The device utilizes detachable dies and punches, allowing for adjustment of die placement based on cup size. A conveyor belt below the die transports the cut cup pieces to a horizontal plate, and a push rod controls the vertical movement of the horizontal plate, enabling automatic stacking of the cut cup pieces. However, the following drawback remains: the die-cut paper pieces easily get stuck in the die, affecting subsequent paper sheet extraction. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-efficiency cutting device for paper cup production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-efficiency cutting device for paper cup production includes a frame. A hydraulic column is fixedly installed at the top center of the frame, and a cutting blade is fixedly installed at the movable bottom end of the hydraulic column. The cutting blade is located inside the upper part of the frame. A material discharge port is opened at the bottom end of the frame. A fixed seat is fixedly installed at the bottom end of the inner wall of both ends of the frame, and a blade holder is fixedly installed at the top center of the fixed seat. A material discharge channel is opened between the blade holder and the fixed seat. An installation cavity is provided between the inside of the blade holder and the inside of the fixed seat. An air inlet pipe is fixedly inserted into one side of the installation cavity, and a flow divider ring is fixedly connected to the output end of the air inlet pipe. A guide pipe is fixedly connected to both ends of the flow divider ring, and multiple first branch pipes are fixedly connected to the opposite ends of the two guide pipes at an angle. A second branch pipe is fixedly connected to the top end of the guide pipe. Multiple air outlets are opened at both ends of the material discharge channel.

[0007] Preferably, a first guide roller is rotatably installed on both sides of the inner wall at both ends of the frame, and a second guide roller is rotatably installed in the middle of the inner wall on both sides of the frame, with the two second guide rollers located on both sides of the top of the tool holder.

[0008] Preferably, the discharge channel is matched with the cutting tool.

[0009] Preferably, the diversion ring is located outside the discharge channel.

[0010] Preferably, all of the multiple air outlets in each column are tilted downwards, and the inlet end of each air outlet is sealed to the outlet end of the first branch pipe.

[0011] Preferably, the two second branch pipes penetrate the mounting cavity and extend to the outer side of the top of the tool holder, the upper end of the second branch pipe is hook-shaped, and the outlet end of the second branch pipe is inclined downward.

[0012] Preferably, the tool holder is made of a thermally conductive material.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model proposes a high-efficiency cutting device for paper cup production. Raw paper is conveyed at the top of two first guide rollers and two second guide rollers. When the hydraulic column extends, the cutting blade lands on the top of the blade holder, cutting off the paper pieces from the cup. The paper pieces fall inside the discharge channel. Because multiple air outlets in each row are inclined downwards, and the upper end of the second branch pipe is hook-shaped with its outlet inclined downwards, when the air inlet pipe delivers airflow into the distribution ring, the two second branch pipes spray airflow at an angle towards the top of the discharge channel. Multiple first branch pipes in two rows guide airflow into the air outlets, causing the two rows of air outlets to spray airflow downwards at an angle. This allows the paper pieces inside the discharge channel to be discharged downwards by the two sets of airflows, facilitating the smooth and rapid discharge of the paper pieces from the discharge channel and preventing paper pieces from getting stuck and affecting paper collection and subsequent paper processing.

[0015] 2. The present invention proposes a high-efficiency cutting device for paper cup production, in which the blade holder is made of heat-conducting material, which can quickly dissipate the heat generated during paper cutting, and the first and second branch pipes spray airflow around the blade holder, which helps to accelerate the heat dissipation efficiency of the blade holder and the cutting blade.

Detailed Implementation

[0021] Reference Figure 1-4 A high-efficiency cutting device for paper cup production includes a frame 1. A hydraulic column 4 is fixedly installed at the middle of the top of the frame 1, and a cutting blade 5 is fixedly installed at the movable bottom end of the hydraulic column 4. The cutting blade 5 is located inside the upper part of the frame 1. A material discharge port 6 is opened at the bottom end of the frame 1. A fixed seat 7 is fixedly installed at the bottom end of the inner wall of both ends of the frame 1, and a blade holder 8 is fixedly installed at the middle of the top of the fixed seat 7. A material discharge channel 9 is opened between the blade holder 8 and the fixed seat 7. An installation cavity 11 is provided between the inside of the blade holder 8 and the inside of the fixed seat 7. An air inlet pipe 13 is fixedly inserted into one side of the installation cavity 11, and a diverter ring 12 is fixedly connected to the output end of the air inlet pipe 13. A guide pipe 14 is fixedly connected to both ends of the diverter ring 12, and multiple first branch pipes 15 are fixedly connected to the opposite ends of the two guide pipes 14 at an angle. A second branch pipe 16 is fixedly connected to the top end of the guide pipe 14. Multiple air outlets 10 are opened at both ends of the material discharge channel 9.

[0022] In this utility model, first guide rollers 2 are rotatably installed on both sides of the inner wall at both ends of the frame 1, and second guide rollers 3 are rotatably installed in the middle of the inner wall on both sides of the frame 1, and the two second guide rollers 3 are located on both sides of the top of the knife holder 8.

[0023] The discharge channel 9 is matched with the cutting blade 5;

[0024] The diversion ring 12 is located outside the discharge channel 9;

[0025] Each column of multiple air outlets 10 is tilted downwards, and the inlet end of each air outlet 10 is sealed to the outlet end of the first branch pipe 15.

[0026] Two second branch pipes 16 penetrate the mounting cavity 11 and extend to the outer side of the top of the tool holder 8. The upper end of the second branch pipe 16 is hook-shaped, and the outlet end of the second branch pipe 16 is inclined downward.

[0027] The tool holder 8 is made of heat-conducting material.

[0028] Working principle: The raw paper is conveyed at the top of the two first guide rollers 2 and the two second guide rollers 3. When the hydraulic column 4 extends, the cutting blade 5 falls on the top of the blade holder 8, and the paper of the paper cup is cut off. The paper falls into the discharge channel 9. Since the multiple air outlets 10 of each row are inclined downward, the upper end of the second branch pipe 16 is hook-shaped, and the outlet end of the second branch pipe 16 is inclined downward, when the air inlet pipe 13 delivers airflow to the diversion ring 12, the two second branch pipes 16 spray airflow at an angle towards the top of the discharge channel 9. The multiple first branch pipes 15 of the two rows introduce airflow into the air outlets 10, causing the two rows of air outlets 10 to spray airflow at an angle downward. Thus, the paper is discharged downward by the two sets of airflows inside the discharge channel 9, which helps the paper to be discharged smoothly and quickly from the discharge channel 9, avoiding the paper from getting stuck in the discharge channel 9 and affecting the collection and subsequent processing of the paper.

[0029] By using heat-conducting material to make the blade holder 8, the heat generated during paper cutting can be quickly dissipated. Furthermore, the first branch pipe 15 and the second branch pipe 16 spray airflow around the blade holder 8, which helps to accelerate the heat dissipation efficiency of the blade holder 8 and the cutting blade 5.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
